Hi, i have a factory unlocked 3G iphone and live in the UAE. Everything was going well and i could use my 3G service also. Then suddenly my 3G stopped working and i was getting message "not connected to internet" when i browse the web after enabling 3G. I then upgraded the version to 2.2 and then 3G was working fine again. Then suddenly it stopped working again. I cant understand the problem, is it because i installed BossPrefs? Someone please help....
